Trust & security
Security

Review Stability AI's data handling policy. API images processed on Stability's infrastructure. Open source self-hosted deployment keeps data private.

HIPAA compliant with BAA. SOC 2 Type II. GDPR compliant for EU deployments. IRB approval for research datasets. FDA-accepted data quality standards.

Privacy notes

Review Stability AI's privacy policy and commercial licence terms for the specific model (open source licence varies by Stable Diffusion version). API usage subject to Stability's terms.

Patient health data processed under strict HIPAA BAA and applicable research ethics frameworks. De-identification and IRB protocols govern research dataset access.

Verdict
Pros
  • $0.003/image pricing is among the most cost-efficient for high-volume commercial image generation
  • Open source Stable Diffusion 3.5 enables fully private self-hosted deployment
  • Largest community ecosystem of fine-tuned models for custom styles via Civitai and Hugging Face
  • ControlNet structure guidance provides advanced creative control not available in simpler APIs
  • 9 million+ patient oncology database is one of the most comprehensive real-world oncology datasets available for pharmaceutical research
  • FDA-accepted real-world evidence from multiple regulatory submissions provides unmatched regulatory validation
  • NLP curation of clinical notes extracts structured data inaccessible through structured EHR data alone
  • Roche ownership provides stability and pharmaceutical partnership pipeline
Cons
  • Company financial and leadership instability creates product longevity uncertainty
  • Open source licence terms require review — commercial use has eligibility requirements by model version
  • API quality for photorealism below premium Midjourney and Imagen 3 for highest-quality outputs
  • Roche ownership creates potential conflict of interest concerns for pharmaceutical competitors as data partners
  • Real-world evidence database access requires partnership agreements limiting accessibility
  • Clinical note NLP accuracy requires ongoing validation — structured EHR data remains more reliable for some variables
